LOCOIEOTIVE AND THE LIKE PROVIDED WITH CONDENSER.

Application filed March 11, 1919. Serial No. 282,050.

T 0 all whom it may concern Be it known that I, FREDRIK LJUNesTRoM, subject of the King of Sweden, residing at Brevik, Lidingon, Sweden, have invented certain new and useful Improvements in Locomotives and the like Provided with Condensers, of which the following is a specification.

Heretofore the employment of a condenser in locomotives has been desisted from, partly on account of the condenser requiring more space than has been available, and partly on account of the inconvenient arrangement of the condenser and the driving motor.

The present invention has for its purpose to facilitate the use of a condenser in locomotives and the like, and to this end the condenser and the boiler are disposed one after the other, each being placed on its separate car frame, besides which the driving' motor as a whole is arranged on the same car frame as the condenser. As will be understood. it is far easier to provide for a long and movable connection between the motor and the boiler than between the motor and the condenser, on account of the vastly different volumes of steam.

An embodiment of the invention is shown in Figure 1 of the accompanying drawing. Fig. 2 represents a detail.

A denotes a boiler car, and B a condenser gether by means of a pin joint it, according to Fig. 2 in such manner, that they are pivotally connected only relatively to each other, but form a rigid system in the longitudinal direction. The high pressure steam piping from the boiler to the steam motor 0 is preferably provided with a joint i, preferably a ball and socket joint, the axis of rotation of which coincides with the axis of the pin it.

On account of this coupling of the cars, the boiler car acts as a leader for the condenser car, i. e. the wheels 6 of the boiler car act as leader wheels for the condenser car 13 or its driving wheels 7.

When the condenser car is substituted for the tender in the present type of trains, the coal is preferably kept in coal boxes on both sides of the boiler. Only a small quantity of water has to be taken with the train, as by the use of a condenser most of the steam may be returned to the boiler in the form of feed water.

hat I claim as new and desire to secure by Letters Patent of the United States is In locomotives and the like, in combination two connected cars, a boiler disposed on one of said cars, a condenser disposed on the other car, a driving steam motor supported solely on the condenser car, the boiler car being placed before the condenser car, a steam conduit from the boiler car to the steam motor, and a joint in said conduit having its axis coinciding with the axis of the connection between the cars.

In testimony whereof I afiix my signature in presence of two witnesses.

FREDRIK LJUNGsTRoM.
